When is Halloween?

Halloween is celebrated on the last day of October, which is the 31st. This year, Halloween is on a Tuesday.

Why do we celebrate Halloween in the UK?

You may be wondering why we celebrate Halloween in the UK. Although indeed, it isn't as popular as in America, the holiday has grown in popularity here. Whether that is because of the super cute Instagram pumpkin-picking pics you can get or not, who knows? However, you would be wrong to think that this is a new craze. Halloween has been celebrated in the UK going back to the Celtic times - that's more than 2,000 years.
